Hi Andrea, I can confirm, that
network.cookieSettings.unblocked_for_testing is indeed fixing this for me. But since this pref looks like it will not stay long, I would like to fix this with the worker approach. You said you would like to move this discussione to IRC, where can I find you? Thanks for your help! _______________________________________________ dev-platform mailing list dev-platform@lists.mozilla.org https://lists.mozilla.org/listinfo/dev-platform
